Open Clip Art might be a good inclusion for the CD/DVD, it has recently reached version 16. While the ~80MB might not be a problem for broadband users, it might not be so good for those still on dial-up.
Please ignore this if it has featured recently, but I have not noticed it and without the disc search facility working I can't easily tell.

Haha I remember 'hearing' a live performance of that on R3 sometime last year (or the year before). Apparently the BBC had to disable their automatic system that cuts in after three minutes of silence...
